i just installed xp pro on my machine also, and have the same card, only the problem im having is that my machine completely freezes with a high pitched squeal coming from the speakers! reloading the factory xp drivers dont seem to make any difference, the nt drivers wont work, and creative has NO SUPPORT for this card at all... i *really* dont want to have to boot into win98 or linux when i want to listen to mp3s or anything but the system beeps... any other ideas, other then have to buy another sound card for this o/s? *exasperated sigh*
